A longitudinal analysis of the network structure of internet gaming disorder and its associations with distress

Concerns have arisen regarding the possible addictive nature of videogames, resulting in the provisional recognition of internet gaming disorder (IGD) as a behavioural addiction. However, this classification remains controversial, with arguments abounding regarding its structure and nature. Therefore, the present study examined the network structure/characteristics of nine IGD symptoms and three distress behaviours (i.e. depression, anxiety, and stress). A sample of 462 adults (Mage = 30.8. [SDage = 9.23]; 320 males [69.3%]) were surveyed regarding their experience of IGD symptoms and distress behaviours using the Internet Gaming Disorder Short Form (IGDS9-SF) and the Depression, Anxiety and Stress Scale (DASS21) respectively. Subsequently, a network analysis was undertaken using R. IGD symptoms were found to be stable both cross-sectionally and over time. They were associated with, yet distinct, from, depression, anxiety, and stress. The most central symptoms within the network in terms of expected influence were tolerance, persistence, and stress. With a pathway between depression and mood modification providing the 'bridge' between IGD and Distress. The findings support the conceptualisation of IGD as a distinct construct (i.e. behavioural addiction). Further implications for the identification and treatment of IGD are discussed.
